HEEL-GOUGING- MACHINE.

Application led February, 1922. SerialNo. 535,015.

To all whom 25 may concer/a:

Be it known that I, DENNIS PARKS, a citizen of the United States, residing inthe city of St. Louis and State o-fMissouri, have invented new and useful Improve ments in I-Ieel-Gouging Machines, of which the following is a specification.

This invention relates to an improved machine for use'in removing a portion of the material from the upper side of a heelblanl for the purpose of providing a concave recess forming a seat to receive the heel portion of the sole.

It has been the common practice heretofore, to provide this recess by attaching a z rand around the upper part of the heelblank, particularly in the case of whole lift heels. In heel-blanks formed of pieced lifts, attempts have been made to provide this recess by gouging out the central Y portion of the upper lift from near the back to thebreast edge of the heel. In either case, that is to say, where the use of a rand, or gouging, has been employed, the heelblanl; is placed in a mold and subjected to very great pressure in a suitable compress.

In the gouging operation as heretofore practiced, the cut was madefrom a point near the back of the heel-blank and extended in an inclined direction to the breast. The recess thus formed doesV not conform in shape either to the mold of the compress or to the rounded configuration of the heel portion of the sole to which it is to be applied. The desired shape is imparted in the compress, but owing to the unequal depth of the gouge and its lack of co-nformity in shape to the mold, the heel-blank would be subjected to greater pressure at some point-s than others and very often the leather of the heel-blank would be `blackened or burned at such points.

It should be stated that where a leather board is used, the bottom lift, that is, the

one next to the sole, may be readily provided vention to provide a gouging machine which Will enable a concave recess tobe provided in the top of the heel-blank ofV uniform` depth from the point of incision. of 'the cutter to the breast of the heel, theJ recess thus formed conforming in shape land extension to the heel portion of the sole which is to be seated therein, and enabling the heel-blank to be compressed in the mold' of the compress with the application of uniform pressure throughout, thus4 'avoiding the undesirable burning of the heel-blank.

In addition to the above general'object, the invention has j for subsidiary objects, improved means for centering the heel-blank relative to its line of movement as it passes to the gouge, to provide that'the recess to be formed in the top of the heel-blank by the gouge shall be symmetrically disposed with reference to the longitudinal center of the heel-blank; to provide novel means for adjusting the machine to accommodate'heelblanks of different heights, and to provide certain novel details of construction whereby the general and subsidiary object-s of the invention are accomplished.--

The invention .is illustratedl in the accompanying drawing in whichv Figure l isa planview of the machine; Figure 2is a longitudinal,sectional view of the upper portion'thereof taken on the line 2 2 of Figure lA and 'illustrating the position of the heel-blank prior to thev beginning of the gouging operation; Figure 3 is a similar sectional view showing a portion of themechanism Villustrated in Figure 2 but showing the position of the parts as the heel-blank is being gouged.v

Figure 4 is a plan view of a heel-blank which has been gouged to provide a recess in its upper side; and .j

Figure 5 is a perspectiverview ofthe devicerfor centering or positioning the heel liftV as it passes to the gouger. v Referringnow to the drawing, the'numeral 1 indicates a main fra-me which may be mounted in anysuitable manner, VAas by being bolted tov a table or other character ofsupport vor by being supplied with legs or standards, the particular manner of mounting the frame not being shown. Journaled in side bars 2 0fl this main `frame is i gouger is adjustably secured on the inclined`v` a shaft 3 having secured on one end a clutch member 4. Rotatably mounted on the shaft is a pulley 5 which is provided with a clutch member 6. The numeral T indicates a pulley shift which embraces opposite sides of an annular flangej8 sur. rounding the hub of the pulley and is pivotally mounted at 9 on the bracket 10 secured on a frame member 2 and is `further provided with a handle 11 for turning it in one direction or the other to-move the clutch member 6 into orv out of engagement with the clutch member 4. The pulleyv is driven by an ordinary belt (not shown) from a suitable source of power. on the shaft 3 ,adjacent to the inner sides of the'frame members 2 Aare two sprocket wheels12 and loosely mounted on a shaft 13 at the opposite end of the frame arev two sprocket wheels 14, the shaft 13 being slidably mounted at its end in slots 15Vprovided in the side frame members 2v and being screwthreaded at either end to rew ceive the threaded portion of set screws 16, the smooth shank portion of which are rotatably mounted'in fiangesl? provided at the ends of the frame members 2 and the ends of which set screws bear 'against the outside of said flanges. By turning these set screws in a clockwise direction, the shaft 13 may be moved outward to adjust the tension of sprocket chains 18 mounted on the two sets of sprocket'wheels 12, 14. The

sprocket chains 18 arev connected at two or more points by parallel cross-bars 19 which act as push bars to move the lheel-blanks into engagement with a gouger 20.v This under side` of the solid portion 21 of a casting which extends substantially from end to end of the frame and is located between the side frame members 2; This vcasting is hollowed out on itsunder side'beyond the gouger 20, as indicated at 22, and provides on its upper side a flat surface forming a table 23.

a transverse slot 24 through which the gouger 2O projects toa desired distance abovev the upper surface or table 23 ofsaid casting.. At opposite ends the casting is provided with downwardly curved extensions 25 which extend over and slightly below the respective shafts 3 and 13. The'side frame members .2 are connected ontheir upper sides by two cross-bars 26, 27 respectively, and on the cross-bar'2''. there is mounted a triangular shaped casting 28 in which is mounted a similarly shaped magazine 29, of tin or other suitable material, which is held in position by means of a screw 30 passing through a flange 31 projecting rearwardly vfrom the casting Vand screwed into a block. 32 `fitted in .the .crotch of the magazine 29. l

Secured About centrally of its length,` this upper portion or table, is provided with As heretofore set forth, a leading charac teristic of the present invention is the provision of means for effecting a uniform depth of gouge or recess in the heel-blank. ril`his is accomplished by the mechanism that will now be. described. i

At'the bottom and rear side of the casting 28 is provided a relatively wide rectangular extension 33 which` is transversely bored to receive a pivot pin34. The numeral 35 indicates an arm which is provided on its outer projection, with a relatively fiat portion 42 e formingv a tread or bearing surface for en gaging', the upper side of the heel-blank, as will be`r presently described. ln its normal position the toe 43 of this dog occupies an elevated position, as shown in Figure 2, and after each operation, is returned to this posie tion bymeans of a spring. To this end the pivot 39 is .in the form of an elongated pin, as shownin Figure 1, which projects beyond one side of the dog an-d of the arm 35, and is encircled by a coil spring 44, one end of which is secured to the pivot pin 39 and the other end of which bears against the rear side ofthe dog, as shown more particularly in Figure 2,.thus operating normally Vto hold thedog .in the elevated position shown in this ligure. To provide that the heel-blank passing to the gouger 2O shall be properly positioned or centered with referenceA thereto,. devised the device shown in Figure 5, which comprises a yoke 45 having laterally projecting parallel arms 46 which are pivotally mounted on the pin 34, washers 47 being interposed between said arms and the sides ofthe bifurcated head of arm 35. ,The legs 48 of this centering 'device are inclined inwardly from the inner edges thereof, that is to say, from. the edges which will be first engaged by the rounded end of the heelblank as it passes to the gouger, such inclined'portion'sbeing indicated at 48, so that if the heel-blank is out of position, it will readily slide over one or the other of said inclined sides so that the longitudinal center of the heel will lie midway between the two legs 48 and consequently will coincide with the transverse center of the gouger 20. Secured in alongitndinal recess 49 provided in the upper part of the table 23, is aleaf spring 50, the free end of which projects'A over therecess 24 and is slightly upturned, as indicated at 51, The purpose of ths'spring is to heid the meeded- Ql forward but end portion of the lift elevated until the latter is depressed by the dog 40, as will now be described.

In operation a column of heel-blanks is placed in the magazine 29, the bottom heelblank of the column resting upon the spring 50. The shaft 3 having been placed in rotation by moving the pulley shift 7, the sprocket chain 18 is set in motion by the driven sprocket wheels l2 and one or the other of the push bars 19 will engage the breast edge of the lowermost heel-blank in the magazine and move it over the spring 5() or table 23 toward the centering device 45. The lower end of this device normally rests by gravity upon the table 23 and the device as a whole is of sufiicient weight to offer such resistance to the movement of the heelblank (indicated by 52 in the drawing) that the rounded end of the latter, engaging the inclined sides 48a, will cause the heel-blank to be moved to one side or the other to center the same. As the heel-blank continues to be moved forward, the centering device 45 will be raised, as shown by- Figure 2, and its lower ends will ride upon the heel-blank as the latter moves under it. In the continued movement ofthe heel-blank, its rounded end next engages the projection 4l on dog 40 thereby turning the toe portion of said dog downward, and engagement of the under side of the dog with the heel-blank forces the forward end downward against the resistance of spring 50, this continuing until l the fiat portion 42 of the dog rests upon the" upper surface of the heel-blank. At the time thel heel-blank is pressed Idownward by the movement of dog 40 about its pivot, the under side of its forward portion will be in position overthe upper or cutting edge of gouger 2O and as the dog continues to turn to the position shown in Figure 3, the gouger will have been thereby caused to penetrate the heel-blank to the maximum depth that the adjustment provides. In the continued movement of the heel-blank, a sectionof the under side of the heel-blank will be cut out, in the manner illustrated in Figure 3, the cut extending from the point of incision to the breast of the heel-blank. During the gouging operation, the weight 36 holds the dog 40 in contact with the heel-blank 52 with sufiicient force to hold the heel-blank in iirin engagement with the gouger. heel-blank is passed from under the dog 40, the latter is returned to the normal position shown in Figure 2, by spring 44. The second push bar will then engage another heelblanlr in the magazine and the foregoing operations will be repeated.

In order to render the machine capable of accommodating heel-blanks of varying heights, I provide for adjusting the height of the dog 40 relative to the bed plate or table 23. To this end I mount in the arm bar 26 to embrace the arm 35 to prevent the bar from being accidentally moved too far laterally in one direction or the other.

rFrom the foregoing, it will be lseenthat I provide for automatically causing an incision of 'uniform depth to be made in successive heel-blanks and the removal of the material from the under side of the heelblank of a thickness corresponding to the depth of the incision. It will be understood, of course, that the gouger 2O is transversely curved and the cutting edge slightly rounded so that the recess formed in the heelblank will be of rounded vcontour to correspond with Ythe shape of the heel portion of the sole which it is to receive. It will further be seen vthat by causing the heel-blank to be automatically centered, Il provide for the correct positioning of theY gouge in successive heel-blanks. These blanks, after having been subjected tothe gougingV` opera-- tion and placed in acompress, will ,be subjectedV to uniform pressure at all points and as indicated above, the objectionable heat` ingvor burning of the heel-blank will lbe prevented.
